Science Station 8: Photosynthesis

Photosynthesis: Look around you here at Lonesome! All of these trees are at work right now. Photosynthesis is a process that permits trees to use their leaves to trap the sun's energy in the form of sugar. The leaves store the sugar in cells in the form of glucose for both immediate and later tree growth. Photosynthesis represents a chemical process in which six molecules of water from roots combine with six molecules of carbon dioxide from the air and creates one molecule of organic sugar. Of equal importance is the by-product of this process — photosynthesis is what produces oxygen. There would be no life on earth as we know it without photosynthesis. We need to continue to take care of our trees and forests.
